Also:

I’ve been getting a lot of questions from Dogsters on how to comment on posts. When you see a posting you want to comment on (and I hope you see a lot of those) simply roll your cursor over the link in “woofs” near the top of the posting. Click on “woofs” and that will take you to a page where you can comment.

You can also just bark at me directly. That works really well when you want to suggest a post subject (and I appreciate those!).
